kbuild: reintroduce ALLSOURCE_ARCHS support for tags/cscope

This patch reintroduce the ALLSOURCE_ARCHS support for tags/TAGS/ cscope targets. The Kbuild previously has this feature, but after moving the targets into scripts/tags.sh, ALLSOURCE_ARCHS disappears. It's something like this: $ make ALLSOURCE_ARCHS="x86 mips arm" tags cscope Signed-off-by: Jike Song <albcamus@gmail.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
